Kilner Clip Top Jar
Soda-lime glass jar with a hinged glass lid, natural rubber seal, and stainless clip - a fully plastic-free sealing jar in the Weck mold, widely available.
The verdict: Plastic-free
The Clip Top seals glass-on-glass: a soda-lime glass jar, a hinged glass lid, a natural rubber ring between the two glass surfaces, and a stainless steel clip that holds it shut. Only glass and natural rubber touch the food - no plastic anywhere in the sealing system. (Kilner's screw-top and twist ranges do use plastic/lined lids; it is specifically the Clip Top and swing-top ranges that are plastic-free.)

The British counterpart to the Weck jar: a hinged-lid preserving and storage jar in the Weck mold, well suited to acidic and fermented foods as well as everyday dry-goods and fridge storage. Sold in a range of round and square sizes.
Pros
- Fully plastic-free seal (glass + natural rubber + stainless clip)
- No metal-to-food contact - good for acidic/fermented foods
- Widely available and inexpensive; replacement rubber rings sold separately
Cons
- Rubber rings wear out and should be replaced periodically (roughly every 12-18 months)
- Rings are hand-wash only; high dishwasher heat degrades the rubber
- Glass is breakable; the clip mechanism is fiddlier than a screw lid
Notes
- Genuine Kilner replacement seals are natural rubber - verify you are buying Kilner rings, not generic silicone substitutes, if seal material matters to you
